Method for making a bridoon

ABSTRACT

A method for the manufacture of a bridoon particularly suitable for horses constructed of a rust-proof steel whereby at least two pipe pieces are tapered on at least one end thereof and flatened so that a ring can be welded on the tapered flatened end and adjacent rings joined together. On the opposite ends of the pipe are welded olive-shaped jackets provided with enlarged rings for receiving and mounting the bridle.

Theconically-shaped parts are pivotably connected to each other. The bridlegear is connected on each opposite open end of the bridoon rings. Thesetypes of bridoons are subjected to a relatively high degree of wear andtear due to tension, friction, and pressure. Furthermore, the bridoonsshould be corrosion proof. These bridoons, as is generally known, areinserted into the mouths of horses so that the bridle gear can beconnected to rings provided on each of the free ends of the bridoons.

There are conventional bridoons which are made of German silver and rustproof or stainless steel. The individual parts of the bridoon are formedby casting. The bridoon is therefore rather heavy, and puts anunnecessary strain on the horse. Some conventional bridoons are casthollow from German silver. It has not previously been possible to cast ahollow bridoon from rust proof super refined steel. However, only thisnoncorrosive material is sufficiently hard to withstand the relativelyhigh degree of wear and tear to which the bridoon is subjected.

Accordingly, the present invention provides a bridoon of theabove-mentioned type made of rust proof super refined steel which isvery light in weight. The invention provides a method for making abridoon wherein the bridoon is formed by a plurality of pipe pieces madeof rust proof super refined steel which are tapered on one end. At leasttwo rings are provided at their tapered ends and are joined together bymeans of welding. On the opposite ends of the pipe pieces, taperedolive-shaped or ovoid jackets are mounted which are also made of rustproof super refined steel. Rings for mounting the bridle gear areprovided on the oliveshaped jackets.

In another embodiment of the invention, the cylindrical hollow parts ofthe bridoon are made of deep drawn rust proof sheet metal with the freeends being tapered and bent. At leasttwo rings made of rust proof superrefined steel are welded to the open ends of the bridoon. Bores areprovided on the other ends of the bridoon for mounting the rings whichfasten to the bridle gear. With this latter method, it is possible tomake the individual bridoon parts either with relatively thin rust proofdeep drawn sheet metal, or super refined steel pipes, to provideresulting in a hollow bridoon.

It is therefore an object according to the present invention to providea method for making, and a bridoon constructed of rust andcorrosion-proof steel, or stainless steel which is hollow in design andlightweight.

It is another object according to the present invention to provide amethod for fabricating, and a bridoon which is simple in design, easy toconstruct and reliable in operation.

Other objects and features of the present invention willbecome apparentfrom the following detailed description considered in connection withthe accompanying drawing which discloses the embodiments thereof. It isto be understood, however, that the drawing is designed as anillustration only and not as a definition of the'limits of theinvention.

In the drawing wherein similar reference characters denote similarelements throughout the several views:

FIG. 1 is a plan view of one embodiment of the inventive bridoon;

FIG. 2 is a cross-sectional view taken through Section [-1 of FIG. 1;

FIG. 3 is a view of an open connecting ring;

FIG. 4 is the cross-sectional view through an oliveshaped jacket, and;

FIG. 5 is a partial sectional view of a further embodiment of a hollowbridoon.

Referring to FIGS. l-4, there is shown one embodiment of the inventivebridoon I consisting essentially of two tapered pipe pieces 2, pivotablyconnected to each other. These parts are made of rust proof superrefined steel pipes which are initially cut to predetermined lengths.Each individual part is tapered at one end. The tapered end is thenflattened. Thereafter, the connecting rings 3, which are initially openas shown in FIG. 3, are connected to each other, and their open ends 7are pressed together. Each ring 3 is then welded to the flatened end ofpipe pieces 2.

A jacket 4 is welded onto the other end 8 of pipe piece 2. Jacket 4 isalso made of a rust proof super refined steel pipe and is also taperedon both ends, so as to form an olive-shaped configuration. Fasteningparts 5 are mounted on olive-shaped parts 4. A ring 6, also made of rustproof super refined steel is provided on the bridoon to receive and holdthe bridle gear. The hollow bridoons are extremely light in weight, incontrast to conventional bridoons.

The further inventive embodiment of FIG. 5 is a bridoon 11 wherein thecylindrical hollow part 12 essentially consists of deep drawn rust proofsuper refined sheet metal. Parts 12 are then tapered and bent at theiropen free ends. The open end 14 is flatened to mount ring 13. Theconnection between pipe part 12 and ring 13 is performed by welding.Pivotable mounting rings 16 which receive the bridle gear bores 15 areprovided at the far end of jacket 12. Rings 16, also made of rust proofsuper refined steel, are mounted in bores 15.

While only a few embodiments of the present invention have been shownand described it will be obvious that many changes and modifications maybe made thereunto without departing from the spirit and scope of theinvention.
